Abstract

PURPOSE:To carry out control of high accuracy through a simple construction, by providing a speed detection circuit which detects a speed in terms of the secondary voltage of an induction motor and is not affected by the fluctuation in the voltage of power. CONSTITUTION:A detector 19, which detects the fluctuation in power, receives a power voltage from the secondary side of a power feedback transformer 6 to supply a fluctuation component signal K to a divider 20. A secondary voltage signal is applied to the divider 20 and divided by the fluctuation component signal K to produce an output VF'. This output is applied to an adder 10 so that a bias quantity VR is added to the output. The output is then supplied as a speed feedback quantity VSF to a comparator 12. As a result, the fluctuation in power is compensated to control a speed.
